Alex Levin 9e8dd06cd4 mb/google/volteer: Add delay to WWAN GPIO init sequence 
Based on Fibocom HW user manual RESET should be deasserted at least 20ms after the power on pin.
The design for the reset pin is open drain connected to a pull up, so it is set to high-Z (configured as GPIO in) after 20ms.

BUG=b:152013143
BRANCH=none
TEST=traced the signals using a scope to verify timing is met.
